Junction Deposit Carbonate Study Chemical Maps
Chemical mapping (energy dispersive x-ray spectroscopy) data of replacement microstructures in carbonates from the Junction gold deposit near Kambalda in the Yilgarn Craton, Western Australia. Maps show relationships between phases as calcite is replaced by dolomite and siderite. Included are the Bruker composite files that contain spectra for each... more point on the map, images of chemical maps for individual elements and composite RGB maps showing Mg, Fe, and Ca respectively. For composite images, chemistry is overlain on back scattered electron images to give the image the resolution of the BSE image but chemical data from the x-ray spectra. less

Data were collected using the Bruker Esprit software. Maps were exported directly for the software as raw counts.
The data were collected from sample 250 as described in Polito et al. (2001), Australian Journal of Earth Sciences, 48, 833 - 855
The data were collected and processed by Mark Pearce

Examining the relationship between damage and chemical reaction fronts around gold deposits. The project combines microstructural and microchemical analysis techniques to examine in detail the relationship between deformation and alteration and how these relate to gold mineralisation
Imaging of chemical variations during replacement reactions
Quantitative and qualitative imaging and chemical mapping was carried out to complement crystallographic studies of mineral replacement reactions from ore bodies.
